TROLLEY-WIRE GUIDE.

SPECIFICATION forming part of Letters Patent No. 786,832, dated April 11, 1905. App1imionfuedcrune4, 1904. semina. 211,134.

T LZZ whom, it may concern.-

Be it known that I, STEWART P. MOMULLEN, a citizen of. the United States, residing at Sioux City, in the county of. Woodbury and State of the wire and preventing it from becoming dei tached.

It is well known that in the operation of a car the trolley-pole frequently comes off, thus causing delay. My invention holds the trolley-Wheel iirmly against the wire under all ordinary circumstances, and if from any cause it becomes separated from the wire it will be instantly readjusted. This object is attained by the construction shown in the accompanying drawings, in which- Figure l is a view of my invention in side elevation. Fig. 2 is an end view of the same, and Fig. 3 is a longitudinal sectional view of Fig. l. Fig. 4 is a side view of my invention as used in operation.

Referring now to the illustrations, in which similar parts are designated by similar letters of reference, A is a ferrule adjusted to the outer end of the pole F, being secured thereto by the screw-bolts a a in the openings Z Z in the lipped edges A A of the ferrule. At the outer end of the ferrule are the two flat paralle] extensions B B, usually adapted toY inclose the wheel. Two curved parallel arms C C, forming nearly an obtuse angle and connected just above the angle by the cross-piece c, are pivotally secured at the angle to the outer end o1c the extensions B B by a bolt CZ, the angle or curve of the arms opening downward. The trolley-wheel D is secured between the outer ends of the arms by a bolt e, on .which it is adapted to rotate.` A spring E is formed by securing the loop of heavy wire to the outer extremity of the lipped edges of the ferrule, winding the wire around the bolt Z and securing the free ends of the wire to the lower ends of the arms. The spring pushes the lower parts of the arms downward and away from the pole and forces the upper parts of the arms correspondingly upward, thus constantly pressing the wheel upward against the wire. When the wheel and pole are normally situated with reference to the wire, the lower parts of the arms are nearly parallel with the pole, as seen in Fig. 4.V A chain g. connecting the lower ends'of the arms, prevents them from turning too far. If the wheel becomes disconnected from the wire, the arms assume the position shown in Fig. 1. The forkedY extensions H H are secured to the arms C C to guide the wheel back to the wire when it becomes detached. They are made vof heavy wire, one end of which is secured to the outer end of the arm, and the wire bent so as to form a long loop with parallel sides. The outer end of the wire is secured to the upper part of the arm near the outer point of the angle, so as to partly encircle the wheel. p The two wires diverge from the point where they leave the wheel, at which the space between them corresponds to that between the Hanges of the` wheel.

It will be seen that my device is wholly automatic, requiring no assistance from the motorneer in its operation.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is*

l. In a trolley-wire guide, the combination of curved parallel arms 'pivotally secured to the outer end of the trolley-pole, the curve of said arms opening downward, a flexible connection for the lower ends of said arms, a trolley-wheel pivotally secured between the outer ends of said arms, and a spring E adapted to force the lower ends of said arms downward and away from the pole and to press the upper ends of said arms upward in the direction of the wire, substantially as described.

2. In a trolley-wire guide, the combination of curved, parallel arms pivotally secured to the outer end of the trolley-pole, the curve of said arms opening downward, aspring adapted to pressthe lower ends of said arms downward and away from the pole and force the IOO upper ends of said arms upward in the direction of the Wire, forked extensions secured to the outer ends of said arms, the lower ends of said extensions partly encircling the trolley- Wheel, with a trolley-wheel pivotally secured between the outer ends of seid arms, substantially as described.

In witness whereof I have hereunto aixcd my s1gnature1n tlie presence of two witnesses.
